The most likely culprit here is you have your TV set to expect "Black" will be sent from the player with the numeric value 0 instead of the normal (for Home Theater use) 16. Look for a setting (in the TV!) related to Black Levels which offers only TWO choices -- not some sort of slider or numeric setting with multiple choices -- and try switching the TV to the other of those two choices.

Thanks very much for your feedback, Bob. While I did not find a 0 vs 16 switch problem, I do believe that the TV is "the culprit". I play several sources through my 205: Disc Media, Movies from my NAS Drive, XBOX One, etc. I discovered that when the TV is set to Auto, some of the calibration settings were getting changed. For example:
* Watch UHD - Calibrate
* Watch DVD - Black level changed
* Watch XBOX - Black level changed, live color off
* Watch NAS drive movies - Black level changed
Presumably this is due to each of the auto modes, even though they are all feeding the Sony via the same HDMI connection. I also found that although every reviewer calibrated the set at the default setting of 50, I need to drop mine down to 38. My home theatre is pitch black.
In any case, when the black level of the TV is put back down to 38, I get glorious blacks.
